I properly installed CLI. In a command window, I enter:

sfdx force:auth:web:login -d -a DevHub

in order to log in to the trial Dev Hub that I created. The aforementioned command opens the Salesforce login page in the web browser, so I log in using my Developer Hub Trial Org credentials and click Allow. After that, web browser show me an error: "This site can't be reached. localhost took too long to respond".

This is the URL that Salesforce use after I authenticate in the browser: http://localhost:1717/OauthRedirect?code=aPrxbOND3gL_2LbSR7rKPdvD0XBVk2YpErl3pphY2f3xvZ1wf5SSPJByDleRLPMtzCQWnNGAdg%3D%3D&state=f2f8254fac23

I don't know what happen.

I keep receiving the "Houson, we have a problem," message - I've logged in before and I can't reset my password. What should I do?

Hi,
 I have a developer account and i would like to login to Sandbox (https://test.salesforce.com) but i am unable to login to test.salesforce.com
